Grilla Grills is now... the first Pellet Grill maker to offer a controller that works as a PID or , a traditional timed on/off pellet feed setup. They are touting this as the best of both worlds.
I personally think it's more marketing hype than real value, but hey, it is interesting that you could choose which to use on one of their grills in the new model year.
If they had offered WiFi too, I might have bought a controller to use on some other pellet grill I own, but without WiFi, it doesn't have enough appeal to me.
